The watch is powered by the Co-Axial Master Chronometer Calibre 8912 with automatic bi-directional winding. In the movement is a Silicon “Si14” balance spring for Omega’s free-sprung balance, a Co-Axial Escapement, and two barrels mounted in series, providing the watch a 60-hour power reserve. That movement has already been featured in various versions of the Planet Ocean, including the Ultra Deep and O-Megasteel models, as well as the PloProf and the Seamaster 300 Master Chronometer models; now it is part of the Planet Ocean’s new core collection.
The biggest update for most buyers is probably the aesthetics. The case still retains a slight lyre lug twist from previous versions, but is much more angular, featuring sharp edges, polished chamfers, and brushed sides. The crown guard is more pronounced. But you know what isn’t pronounced? The second crown for the manual helium release. It’s so not pronounced that it’s completely gone. The slimmer flat link bracelet has also been redesigned, meeting the lugs at their 21mm width in a way that appears nearly completely integrated into the case. The bracelets (tapering to 16.5mm) are adjustable to six positions and are equipped with Omega’s extra diver extension.
